Answer:

The correct answer is d) vertically upwards

Explanation:

Using Fleming’s left-hand rule, the wire’s force acts vertically upward.
The index finger indicates the direction of the magnetic field, the middle finger represents the direction of the current, and the thumb represents the direction of the force received by the wire.
